Unity_EnvironmentShaders

This Repo contains some of my environments shader experiments in Unity3D

Grass

Some Grass Shaders

Ivy

Some Ivy Shaders

My take on an Ivy shader:

• Generate a few geometric copies (hulls)
• Offset based on normal * value.
• Sample Leaves from a base diffuse map.
• Use color ramp to specify depth for clipping cutoff values.
• Alternate UV offsets.

Features: Forward (Custom lighting) + Deferred (PBR Lighting)

Inspiration:

• Keijiro's Standard Geometry Shader
• Brute Force's Grass
• Shahriar Shahrabi's Volumetric Grass
• Inigo Quilez's Biplanar Mapping

Unity 2018.4 Should work in any project with a GPU that allows Geometry Shaders.
